I thought of creating a VMware Image of Sahana with a easy download size as much as possible. Making changes to Debian or Ubuntu is very much easy and I could have easily created a Sahana VMWare image based on that. But its not nice to expect a user to download a 700MB image to try out Sahana. So I evaluated several ISOs and finally selected DSL which is around 50M in size.
After successfully running the DSL ISO in VMWare I tried to install DSL in a virtual disk.
At first I create the virtual disk with QEMU and modified the VMX file to use it, I expected a SCSI virual disk and I could not get VMWare to recognize the disk I created with QEMU as SCSI.

Just because its virtual do not think licenses also become virtual ;-)
so restriction with per seat licenses,ect apply equally in this virtual domain. Read http://www.vmware.com/download/eula/vmimporter_v20.html carefully ,specially section 3.6

"Licenses required for third-party software. The Software enables you to run multiple instances of third-party guest operating systems and application programs. You are responsible for obtaining any licenses necessary to operate any such third-party software, including Guest Operating Systems."

then read

if you want to share a directory between guest and host OS, then you need to create a shared folder. adding virtual disks won't help you.
Thus create a shared folder to real time share data . how ever you need to have vmtool installed to do this successfully.
